This classic duo makes a delicious spring dinner.
Preheat oven to 450 degrees. On a large rimmed baking sheet, toss leeks with oil; season with salt and pepper. Roast, tossing once, until beginning to soften, 12 to 15 minutes.
Remove leeks from oven, toss with pan juices to coat, and push to edges of baking sheet. Arrange salmon pieces in center, and season generously with salt and pepper.
Return to oven; roast until salmon is just opaque throughout, 10 to 15 minutes (depending on thickness). Serve salmon with leeks and lemon wedges.
Leeks can be extremely dirty and are best cleaned after they've been trimmed and cut. Soak cut leeks in a bowl of cool water; lift them out, replace water, and repeat until no grit remains at the bottom of bowl.
